I cooked a small leg of lamb and there's a nice (smallish) bit of bone in the fridge with some pink meat adhering. I know Fraser would love it, but is it safe to give a cooked bone to him? It still has marrow inside and the roast was cooked to rare. I read somewhere that cooked bone is brittle and not good for chewing, but this one as I say was in the middle of a pink rare roast and maybe isn't as brittle? Want to be safe in what I give him to chew.
